CHIP-8 Emulator/Interpreter

Implemented with the original CHIP-8 specs in mind.
As the options to enable/disable some quirks from variants are added, implementations for S-CHIP and XO-CHIP might be included.

Compiled and tested on Linux only. Has SDL2 as dependency.

Building

Just run make while in the project directory.

Running

chip8 PATH [--freq <int>] [--sound <double>] [--bg "#RRGGBB"] [--fg "#RRGGBB"]

note: after running make the binary file is saved in the bin/ directory.
Example: bin/chip8 examples/tingo.ch8 --freq -1 --bg "#000015" --fg "#FFD077" --sound 170

Sound

A sine wave sound is played for the buzzer. You can adjust its frequency with the --sound <double> flag.

Keys

This is the CHIP-8 keypad layout on a QWERTY keyboard:

     QWERTY                      CHIP-8
[1] [2] [3] [4]             [1] [2] [3] [C]
